HERBICIDAL COMPOSITION Russian patent published in 2022 - IPC A01N25/30 A01N33/02 A01N57/20 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to herbicidal compositions. An aqueous herbicidal composition contains from 100 to 750 g/l (in the form of acidic equivalents) of glyphosate or its agriculturally acceptable salt and from 1 to 30 wt.% of ethoxylated amine of composite ester, where the specified ethoxylated amine of composite ester has the formula (I): (I),

where: a) R, R’, and R”, each independently, is an alkylene group with 1-8 carbon atoms, b) X, Y, and Z is selected from H, O-(CH₂CH₂O)_nH, O-(CH₂CH₂O)_n-COR’’’, or O-COR’’’, and one of X, Y, and Z is O-(CH₂CH₂O)_n-COR’’’ or O-COR’’’, where n=1-40, and R’’’ is a saturated or unsaturated C₆-C₃₀alkyl group; provided that: i) if one of X, Y, or Z is O-(CH₂CH₂O)_n-COR’’’, each of two other substitutes is independently H or O-(CH₂CH₂O)_nH; ii) if one of X, Y, or Z is O-COR’’’, two other substitutes are H or O-(CH₂CH₂O)_nH, and at least one of them is O-(CH₂CH₂O)_nH, where the specified ethoxylated amine of composite ester of the formula (I) is a product of a reaction of saturated or unsaturated C6-C30 aliphatic monocarboxylic acid and tertiary hydroxylamine, where ethoxylation is carried out directly on tertiary hydroxylamine before esterification or on a product of an esterification reaction. The aqueous herbicidal composition is used in a method for destruction of weeds in crops of agricultural plants and in a method for control of weed growth.

EFFECT: proposed aqueous herbicidal composition has improved physical and chemical indicators, in particular, shows high stability and has an improved ecotoxic profile.
